RETORT VAPORIZER AND BURNER FOR OIL. AND WATER.

SPECIFICATION forming part o1 Letters Patent No. 435,236, dated August26, 1890.

Application iiled November 30, 1889. Serial No. 382,136. (No model.)

To all whom t may concern:

Be it known that I, MARTIN D. MILLER, a citizen of the United States,residing at Leavenworth, in the county of Leavenworth and State ofKansas, have invented certain new and useful Improvements in RetortVaporizers and Burners for Oil andVater; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

-My invention relates to improvements in that class of vapor-burners inwhich the component parts or elements of the vapor are separatelyintroduced into the burner and are so acted upon within the same as toform the desired combustible gas.

In my improved burner the oil and water are fed into the burner throughseparate pipes and admitted into different chambers to be vaporized,after which they are carried through independent passages to the outletof the burner, where they are united and consumed.

By my improved construction I secure perfect combustion of the gases andovercome the-tendency of the water-gas to extinguish the oil-gas,besides cheapening the cost of the burners of this character; and myinvention consists in certain novel features of the device shown in-theaccompanying drawings, as will be hereinafter described and claimed.

In the drawings referred to, Figure I is a side elevation of my improvedburner with the inclosing-cylinder in section. Fig. 2 is a verticalsection of the same, and Fig. 3 is a` sectional perspective view showingthe several parts detached and in theirl proper relative positions.

Referring to the drawings by letter, A desi gnates the oil-inlet pipe,and B the water-inlet pipe, which may lead from any suitable source ofsupply and have their upper ends communicating with the chambers orcompartments C D,respectively. These chambers are formed by the castingsE F, which are circular in their construction, and are provided with theinternal partitions G and the central circular ribs H, as shown. Thecastings are placed together around the central airtube I, so that theirribs and partitions coincide, as clearly ber D is provided with anopening or perforation L, through which the water passes to a shallowcup or pan M, formed in the upper side of the upper casting. A spreadingplate or cup N is fitted on the upper end of the central air-tube. andbears on the upper casting E, so as to cover the cup or pan M therein. Achamber O is thus provided, in which the water or steam collects, andfrom which it escapes through the small openings Il, said openings beingformed by shallow grooves cut in the edge of the cup or pan on the upperside of the casting. A diaphragm or cap Q is supported by the cup anddirects the steam t0 the ameppening, as will be hereinafter more fullyreferred to. The circular rib of the lower casting is V-shaped incross-section, thereby forming a space or chamber R, and is providedwith the openings S, which furnish communication between the chambers JR.

The lower portion of the chamber R is closed cape. A su pporting-plate Vis arranged below l the plate T, and an asbestus iilling W is arrangedbetween the said plates T V. The plate V is screwed onto the centralair-tube and acts in conjunction with the cup N to secure the severalparts firmly together, as will be readily understood-upon reference tothe drawings. This plate V is further provided with the openings X topermit the initial heat or llame to pass readily to the asbestus andignite the oil contained therein. A retaining-cylinder Y is arrangedaround the several parts just described and supported in any convenientmanner, so as to direct the oil-vapor to the flame-opening.' Thewater-supply pipe may, if so desired, be packed with asbestus, and Ihave so illustrated it.

The construction and arrangement of the several parts of my improveddevice being thus made known,the operation of the same will be readilyunderstood. Oil is admitted through the pipe A into the chamber C andIOO passes from the said chamber to the chambers J R, and from thechamber R it escapes to the asbestus W, which it saturates. The oil iscut off after the several chambers just mentioned are filled, and aninitial llame is then applied to the plate V, so as to ignite the oil inthe asbestus and heat the plate T and the castings E F, thus heating theoil in the several chambers and causing the same to iiow to the openingsU and be consumed until vapor is generated in the chamber C. When theoil is exhausted from the chamber C, that fact will be indicated 'by adiminished flame, and the oil is then again turned on to maintain thesupply. When the castings E F have been sufficiently heated to instantlyconvert water into4 steam, the water is admitted into the chamber Dthrough `the pipe B, as will be readily understood. The water will beconverted into steam in the chamber, and it passes from said chamberinto the chamber O, from which it escapes through the openings Pandcommingleswith the burning oil-gas rising through the cylinder Y, thusproducing a per-4 fect combustion, so that there will be no waste ofheat or fuel. The pressure with which the flames are ejected creates adraft, by which air will be drawn into the burner in suicent quantitiesto produce a complete chemical combination. The necessary draft isfurther provided for by the central air-tube, as air :rises through saidtube and passes through the same directly to the center of the iame.

It will be observed that I have provided a 'very simple device inwhichthe oil and water are separated from each other until they reachthe proper point for ignition, thereby securing a more perfectcombustion than has heretofore been done.

My device maintains a constant gen eration and consumption of gas, andthe oil is converted into gas by its own heat while burning. The water,furthermore, is by the same heat superheated so that it will be injectedinto the iame of the oil-gas by its own pressure to produce ahighly-combustible gas. It will be seen, also, that thesupplypipe ofchamber D is tempered by theinitial lflame at W.

Having thus described my invention,` what "I claim, and desire to secureby Letters Patl. A vaporizer comprising the hollow sectional castingshaving internal partitions provided with transverse openings and fittedtogether, forming the communicating chambers C R, the said chamber Rhaving vapor-exit openings, afire-proof filling arranged below thechamber R, and the plate V, supporting said filling, as set forth.

2. The combination of the central air-tube, the castings mounted thereonand having the internal partitions G and the central circular ribs H,thereby forming the chambers C D J R, the chamber R, having vapor-exitopenings, inlet-pipes for the chambers O D, the plate T below thecastings and forming the bottom of the chamber R, the plate V, securedon the air-tube below the plate T, and the cup Secured on the upper endof the airtube and provided with vapor-exit openings, as set forth.

3. The combination of the central air-tube, the castings secured thereonand having internal partitions, forming the chambers C D J R, andprovided with vapor-exit openings, the pipes A B, entering the bottom ofthe chambers C D, respectively, the plate T, forming the bottom of thechamber R, the plate V, secured on the air-tube below the plate T, thecup N on the upper end of the air-tube, the cap Q on the cup N, and thecylinder Y, surrounding the castings and the pipes A B, as

set forth.

In testimony whereof I affix my signature in presence of two witnesses.
